As the story goes, the Spanish American War taught the US Army that the 30-40 Krag was an inferior rifle to the German Mauser. So they copied the Mauser but with the same .308 diameter 220 grain bullet used in the Krag. They gave it another 200 fps velocity and needed a rimless case for clip loading, resulting in the 30-03 and the 1903 Springfield rifle.

A short time later, they decided that a lighter spitzer bullet was better and settled on a 150 grain bullet (I believe) at 2700 fps. Instead of loading this in 30-03 cases, they shortened the case neck. This required rechambering all the existing Springfields. They called them all back and shortened the barrels one thread, resulting in the 30-06 Springfields having a 23.79" barrel instead of the original 24" barrel.

Why did they go to all this trouble? Why not just load 150 grain bullets in 30-03 cases?

the cartridge was a resign to optimize for the newly developed spritzer bullet. The gun redesign was adjusting to the new cartridge design.

They figured some knotthead would use the longer necked cases and neck them down to something ridiculous like 27 cal.

Say what you want, but the Springfield Armory provide the Army with small arms that worked well for any given time- The Spainish American War was at a time when small arms and cartridges were in transition, TR sorted it out when he became President and the rest of us got a pretty good hunting cartridge out of the deal They shut down Springfield Armory during LBJ's time- much to the loss of the Army!

I'm guessing it was to fix a minor feed issue. Easier to revamp the brass than to revamp the action.

Maybe to keep the ogive of the shorter spitzer bullet out of the case neck?

Who knows?

I think the Spanish had the 7mm Mauser and the Americans had Krags with black powder and trapdoors.

The Germans had the 8x57 in 1905 that would do 2900 fps with 150 gr.
Work up a load to brass yield, back off a safety margin, and you would have the same load 110 years later.

By 1906 the 8mm would be the cartridge to beat.

Yes, I've read or read ABOUT that before.


MY ? is WHY NOT develop the 06?

IMO - NO OTHER cartridge, domestic or foreign, has the successful HISTORY of the "venerable" 30.06

The reason for the reduced neck length was due to the shorter bearing surface of the new pointed bullet.

Frankford Arsenal experimented from May 1906 with a version of the then new spitzgeschoss (pointed bullet) which the Germans had introduced in the previous year. The FA version was a 150 grain flat based design with a long ogive and short bearing surface of 0.255", on an overall length of 1.15". The bearing surface was much shorter than the round-nosed 220gn of the .30/03, and the case neck was shortened to suit it.

It was then found that the long jump to the rifling with the new design in the existing rifles resulted in poor accuracy, so in the latter half of 1906 the chamber specification was changed, resulting in the need to set back barrels on existing rifles, and on October 1906 - after a very short development time, the Model of 1906 was officially adopted.

It didn't quite end there though. Among other things, the bullet design was soon revised to increase bearing length to 0.33" (July 1907) and then, after problems with holding even that bullet in the neck securely, and trying various crimp methods, the bullet was modified to a cannelured form (Feb 1909). With some minor variations that was more or less it until after WW1.

In 1909 too DWM approached the Ordnance Office about royalties for the copying of their S-ball design, and when this was refused it led to litigation, complicated by WWI, which eventually and somewhat circuitously resolved in DWM's favour.

Probably worth noting that there were other bullet designs tried at Frankford Arsenal too. There had been quite a number trialled in the Krag, for example, of all sorts of designs. In the development of the .30/03 there were several types tested too, including various versions of the 220 gn RN (three cannelure, single cannelure, no cannelure, no cannelure and with a taper to the bearing surface from .308" to .307" at the base) as well as a 180 gn solid copper bullet of streamlined shape based on the French Balle D.

There was also, in 1905, a request for a soft-point bullet for the then President, 100 of which were hand-delivered to the White House.

Huntz got it 100% right.
The second reason was to provide Mule Deer with a source of brass from which to form 7x57 cases.

Why did they develop the .30-06? So the Campfire would have something to yammer on endlessly about 110 years later, that's why! smile

I've always wondered why the Army Ord Corps just didn't adopt the 7.65x53, either in 7.65mm or 7.62mm bore, in lieu of the 30-40, 30-03, or 30-06.

Funny how by 1911 We had 7 and 8x57, 3006, 45 Colt, and 45 acp along with their signature guns. Not a rabid fan of any but the Colt, however 104 years ago we already had about everything one could need.

I think this is the logical reason, and the fact, that the 7mm Mauser provided a design model to essentially magnify to .30 cal.

Perfection didn't come until 1925 when it was necked down to .277.

Woo-eee - can you imagine the ripple through the space-time continuum if they had downsized the origin?

Snooty types would be talking all about "that boring ol' fiddy seben" and saying how W.D.M. was overgunned. Instead of cognescenti shooting deer with fast twist .223's they'd be popping them with heavy for caliber 18 grain bullets from 1 in 6 twist .14 Calhouns.

Guys -

I think there is more to the prejudice against the 7X57 and 8X57 that led to developing the 30 cal. and especially since so much was already invested in it.

Col Whelan wrote in "Mr Rifleman" that they considered the 7mm as a US service cartridge, but that they decided against it "largely because of our Navy experience" with the 6mm Lee Straight Pull Rifle, "one of the shortcomings being the extreme difficulty of cleaning and keeping the small bore in good condition with the knowledge of barrel cleaning we then had."

Both the Army and Navy tried a few different calibres during the late 1880s-90s, from .32 down to .22 (.20 was also considered). Rubin's work (and the Swiss 7.5 cartridge, a box of which was acquired for US Ordnance in Paris in 1890) figured in the choice of .30 for the Krag.

The .30-03 was effectively the product of an update of the .30/40, intended to match the velocity of the 7mm Mauser. Initial prototypes included rimmed versions, and then rimless, eventually (and not coincidentally) of a head size and design to suit the Mauser stripper clip.

And all along I thought it was so them fella's in the olden days could come up with the .333 OKH 'cause that K guy liked bigger bullets?

Or maybe it was so that Ackley guy could improve it?:

I'm really thinking it's because "thirty ought three" does not sound anywhere near as cool as "thirty ought six" or even just plain old "ought six" and they realized their mistake. cool

You might be on to something there with the "OH 3" name.

They maybe wanted to change it to "ought six" to keep from getting confused with another "OH 3" from a certain group of islands to the east!

(I've got a couple of those foreign '03s and I think they're OK, too)

They gave it another 200 fps velocity and needed a rimless case for clip loading, resulting in the 30-03 and the 1903 Springfield rifle.

A short time later, they decided that a lighter spitzer bullet was better and settled on a 150 grain bullet (I believe) at 2700 fps. Instead of loading this in 30-03 cases, they shortened the case neck. This required rechambering all the existing Springfields. They called them all back and shortened the barrels one thread, resulting in the 30-06 Springfields having a 23.79" barrel instead of the original 24" barrel.

Why did they go to all this trouble? Why not just load 150 grain bullets in 30-03 cases?

It was actually so some know-it-all could sit around a pub (no forums back then) and proclaim that it was the answer to a question that was never asked.

They developed the '06 so that several years in the future, there would be something with which to compare new cartridges smile

So they could take something perfect and turn into something gayish, as in the 2gay70. LOL.
